Hunt has done nothing wrong, and performed for Australia better than I expected.
Hornby was close to the best fullback in the game IMO but has been covering halfback for too long now at the Dragons.
The best fullback in the game currently IMO is Billy Slater. Suspension marred this season and so its hard to say he deserves to be the Aust #1 (ie displace Hunt etc), but if i were a selector he'd be my pick. He's the forgotten fullback amongst all these topics.
Inglis - fantastic wherever he plays, but I'd have him in the centres.
